Getting Started with ADS-B SAPT

A quick guide to using the ADS-B prediction service

Welcome to the graphical web interface for the Automatic Dependent Surveillance-Broadcast (ADS-B) Service Availability Prediction Tool (SAPT).

This website offers an interactive flight planning form that provides predictions of ADS-B sufficiency for specific flight times and equipment configurations. We tried to make this form simple and intuitive to use; you may find that you can jump right in and start performing predictions without having to read too much documentation.

It also supports an XML-based web service for automated checking of ADS-B sufficiency by flight planning software. To read about the XML service please see our ADS-B XML help page.

A quick legal note: this system is for flight informational purposes only. Submissions to this system do not generate formal flight plans.

We encourage users to download the User Guide [pdf] (7.3MB) to become familiar with the SAPT site and features.
